A2-DB3150 Flashing

[andyd]

Thanks Xyn.

So say for a USA type phone I could use your method to upload a self created "blank/generic" custom file, which will then trigger SEUS to upload to the phone the latest generic USA software? What CDA should I use for North America? I see the ATT/USA one in the downloads section, but is that the customized att one I would need to brand the phone to ATT from generic?

I only really need English on there, otherwise I just need it to be generic and upgradeable through SEUS without all the stupid ATT limitations.

I dont have a data plan with them, but would I be able to set it to use a private in home 3g network? Is there even such a thing? I have seen new routers have 3g in them... Would I still be able to use data through att on a generic phone in the future?

Otherwise, could I use the built in GPS? I saw a few places use preloaded maps to the memory stick and I thought I would try that as well.

Use the "customize_upgrade.xml" from my above post.
@[xyn19], there's already a similar tutorial here:

Use "EDIT" button, like me :)

1) Yes, it should flash your phone to the latest generic America firmware. I have not tried those particular 2 CDA's in my original post but I have read other people have done it successfully. I know the generic Hong Kong CDA worked perfectly.
2) To re-brand it back to ATT, you need to download ATT/Cingular MAIN, FS, and the custom file, and use a2uploader to flash, then copy custom files. SEUS does NOT do it (at least to go from HK generic to ATT).
3) You can set up phone via bluetooth to use your computer's internet access. Computer needs to be running Windows XP (Vista and Mac might work), and needs to be in Workgroup mode, i.e. not setup to connect to a Windows Domain. (Another thread or google it.)
4) Yes, you can use data from ATT with de-branded phones. Make sure you have a correct data plan, or they'll charge you per kB or something like that. You need to get network settings right. (Another thread.)
5) Yes, you can use GPS. I know the following versions of GPS all work!! -- Built-in Google Map, downloaded Google Map(sometimes has connection issues, but I have a workaround), Amaze GPS, Mobile Gmaps. I have not tried Wayfinder, I bet it works too. However, ATT Navigator does NOT work on generic phones, Telenav (who makes ATT Navigator) has not a version for most generic phones. (Another thread.)

Cheers.
